Very Low Distortion Attenuator Plastic Packaged PIN Diodes L Alpha Features @ Low Distortion Design @ Frequency Range from HF to > 2 GHz @ Designed for CATV AGC Applications @ Designed for High Volume Wireless Applications Description The SMP1307 series of plastic packaged, surface mountable, low capacitance (0.3 pF) silicon PIN diodes are designed for use in attenuator applications from 5 MHz to beyond 2 GHz. The thick 175 um | region of these PIN diodes makes them very attractive for use in very low distortion Pl and TEE attenuators commonly used in TV distribution applications. The 1.5 uwS typical carrier lifetime of these diodes results in resistance of 100 O maximum at 1 mA and 10 O maximum at 10 mA. Available in a selection of plastic packages, as a single diode in the small footprint SOD-323, and in a variety of configurations in the SOT-23. Also available in a SOT-5 (SMP1307-027) package as a four diode array designed for insertion in the commonly used 4 diode PI attenuator circuit.
